Senior Estonian diplomat Jonatan Vseviov warns that last week’s Russian incursion was “part of a pattern of unacceptable behaviour, not an isolated event.”

“Recent weeks have seen repeated air and drone incidents in the region, all happening on the background of Russia’s illegal war of aggression in Ukraine,” he said.

Vseviov, Estonia’s former ambassador to the US, also urged Europe to respond strongly, saying that “the fact of the incursion shows our previous messaging has not been clear or credible enough to change the reckless behaviour we face.”

“Our purpose is defensive clarity. If lines are blurred, they must be redrawn – decisively and together. That’s what we’ll aim to do in the coming days.”

On Monday, he went further, telling Estonian media that it was necessary to make the consequences of the incident “sufficiently unpleasant consequences for Russia, so that it doesn’t come to this airspace next time.”
